Abstract

Systems and methods for analyte monitoring, particularly systems and methods for monitoring and managing life of a battery in an analyte sensor system worn by a user, are provided.

What is claimed is: 
     
       1. An analyte sensor system configured to be worn by a user, comprising:
 an analyte sensor; and 
 sensor electronics circuitry electrically coupled to the analyte sensor, the sensor electronics circuitry comprising:
 a transceiver configured to transmit and receive wireless signals; 
 a battery; and 
 at least one processor coupled to the transceiver and to a memory, the at least one processor being configured to:
 determine that a remaining power level of the battery is below a predefined power level, and 
 in response to the determination, cause a change in one or more data transmission operations of the transceiver of the sensor electronics circuitry, wherein the change comprises altering at least one transmission mode for transmitting analyte values, and wherein altering the at least one transmission mode comprises switching from periodically scheduled transmissions of analyte values to an event-based transmission of analyte values, the event-based transmission being associated with one or more analyte-related events. 
 
 
 
     
     
       2. The analyte sensor system of  claim 1 , wherein the analyte sensor system is a continuous glucose sensor system. 
     
     
       3. The analyte sensor system of  claim 1 , wherein the sensor electronics circuitry further comprises a battery measurement circuit coupled to the battery and configured to measure a value indicative of a current power level of the battery, wherein the at least one processor is configured to predict the remaining power level of the battery based on the measured value. 
     
     
       4. The analyte sensor system of  claim 1 , wherein the sensor electronics circuitry further comprises a battery measurement circuit coupled to the battery and configured to measure a value indicative of a current power level of the battery, wherein the at least one processor is configured to predict the remaining power level of the battery based on the measured value and an assumed future usage of the analyte sensor system. 
     
     
       5. The analyte sensor system of  claim 1 , where the change includes a reduction in a radio frequency transmission power level of the transceiver. 
     
     
       6. The analyte sensor system of  claim 5 , wherein the reduction in the radio frequency transmission power level of the transceiver is preceded by a determination that the analyte sensor system is in close proximity of a display device for displaying analyte values received from the transceiver. 
     
     
       7. The analyte sensor system of  claim 1 , wherein:
 the at least one transmission mode comprises one or more bulk transfers of past measured analyte values stored at the analyte sensor system; and 
 the change includes a limitation on the one or more bulk transfers of past measured analyte values stored at the analyte sensor system. 
 
     
     
       8. The analyte sensor system of  claim 7 , wherein the limitation includes a cancellation of the one or more bulk transfers altogether. 
     
     
       9. The analyte sensor system of  claim 7 , wherein the limitation includes a transfer of only part of the stored past measured analyte values in the one or more bulk transfers. 
     
     
       10. The analyte sensor system of  claim 1 , wherein the one or more analyte-related events include a user prompt of data. 
     
     
       11. The analyte sensor system of  claim 1 , wherein the one or more analyte-related events include analyte values exceeding or falling below a threshold analyte value.
